<br>
<tt>Thanks for "another" report :).</tt><br>
<br>
<tt>Questions:</tt><br>
<tt>1) do you do any async for the INVITE in this crash ?</tt><br>
<tt>2) if it is an YES to (1), is the caller party generating the "503 Service Unavailable" (which triggers the crash) - 10.32.20.60 ?? - a really close (from net delay perspective) and fast to answer party ?</tt><br>
<br>
<tt>Regards,</tt><br>
